Definitions

This invention relates to a mining machine of the shearer type adapted to be reciprocated along or adjacent an armoured scraper chain conveyor extending along a longwall mineral face.
such a shearer has been provided with a haulage unit incorporating a power output sprocket, around which sprocket was threaded a portion of a tensioned round link chain also extending along the mineral face, at the goaf side of the conveyor, and being staked at each end of the mineral face.
a mining machine of the shearer type comprises an elongate machine body, housing, inter alia, a power unit for powering at least one rotary, mineral cutting head, and at least one haulage unit mounted on the outside of the machine body and comprising a variable speed motor connected via speed reduction gearing to a machine haulage sprocket adapted to engage progressively rack bars or a chain extending along the mineral face.
the haulage unit(s) may be fitted at the most appropriate location for particular operating conditions and hence is not "handed". Thus the haulage unit(s) may be located on either the goaf side or the face side of the machine.
a brake unit which can be of a fail safe multi-disc type operable either electrically or hydraulically, may be interposed between the motor and the gearing of the or each haulage unit.
the brake unit may be located within a flameproof casing of the motor.
each haulage unit can be hydraulic, it is preferred to employ electric motors, in which case variable speed A.C. motors are recommended.
the motor of each unit may be rotatable about an axis extending transversely with respect to the longitudinal axis of the machine body or may be rotatable about an axis extending parallel to the longitudinal axis of the machine body, in which latter case the speed reduction gearing transmits the drive through 90°, e.g. by incorporating a pair of bevel gears, as the haulage sprocket is rotatable about an axis extending normally with respect to the electric motor axis of rotation.
the drive sprocket could be rotatable about a generally vertical axis, it is preferably rotatable about a generally horizontal axis.
FIG. 1 is a side elevation, from the goaf side, of a shearer type mining machine in accordance with the present invention
FIG. 2 is a plan view of FIG. 1;
FIGS. 3A and 3B are respectively longitudinal sectional views through a haulage unit shown in FIGS. 1 and 2, and
FIG. 4 is a view in the direction of arrow A in FIG. 3A.
shearer type mining machine 1 of the invention having an elongate machine body 2.
Machine 1 is mounted on, and guided by, a scraper chain conveyor 3 seated on a mine floor 4 which extends along a mineral face 5.
the machine 1 is a double-ended ranging drum shearer comprising, at each end of the machine body 2, a gearhead 6 pivotally carrying a ranging arm 7 under the control of a double-acting, hydraulic, piston and cylinder unit 8, the ranging arm 7 carrying a secondary ranging arm 9 on which is mounted a rotary, pick-carrying cutting head 10 to remove mineral from the face 5.
the machine body 2 further comprises a motor unit 11 housing an electric motor to power the two cutting heads 10.
a pair of spaced apart haulage units 12 each comprising a drive sprocket 13 in engagement with a rack element 14 secured to the conveyor 3.
Each sprocket 13 is rotatable about an axis 15 extending laterally of the longitudinal axis of the machine body 2.
Each haulage unit 12 further comprises an electric motor 16, rotatable about an axis 17 extending parallel to the longitudinal axis of the machine body 2, a brake unit 18 and a speed reduction gearbox 19, the haulage units 12 being located outside the machine body 2 and under the control of a unit 20 forming part of the machine body 2 and located between the motor unit 11 and one of the gearheads 6.
the gearboxes 19 each drive through 90° by incorporating bevel gears 21, 22.
the electric motor 16 is preferably of the variable speed a.c. type, while the brake unit 18 is of an electrically or hydraulically operated, fail-safe, multi-disc type.
the brake units 18 are each spring loaded into the braking condition and electrically or hydraulically released from the braking condition.
a haulage unit 12' (similar to unit 12) can also be mounted externally on the goaf side of body 2 depending upon particular operating conditions.
